The player controls a stealthy sub sneaking into top-secret Russian territory, trying to avoid enemy mines through a series of twisty channels, and occasionally needs to replenish the air supply by running through tanks marked "air." Avoid contact with everything that doesn't say "air," in fact. If it looks vaguely familiar, and sounds vaguely familiar, it's no coincidence: Harbor Escape
is a very thinly-disguised, only-slightly-reprogrammed version of Activision's Atari VCS bestseller River Raid
. If anything, the changes made to the graphics to try to make Harbor Escape
look like a new game have done nothing to help the game play, and actually make the game look ugly and amateurish.
